Constructor Detail

BidPoint

public BidPoint(Bid bid,
                java.lang.Double... utility)

Create a BidPoint by given the bid and the tuple of utilities for that bid.

Parameters:

bid - from which the utilities are stored.

utility - tuple of utilities of the bid.

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

string representation of the object.

equals

public boolean equals(java.lang.Object obj)

obj - object to which this object is compared.

Returns:

true if this object is equal to the given object.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

Returns:

hashcode of this object.

getBid

public Bid getBid()

Bid from which the utilities are represented. This bid may be null to save memory.

Returns:

bid which utilities are represented.

getUtility

public java.lang.Double getUtility(int index)

Returns the utility of the bid for the i'th agent (agent A = 0, etc.).

Parameters:

index - of the agent of which the utility should be returned.

Returns:

utility of the bid for the i'th agent.

getUtilityA

public java.lang.Double getUtilityA()

Returns the utility of the bid for agent A.

Returns:

utility for agent A.

getUtilityB

public java.lang.Double getUtilityB()

Returns the utility of the bid for agent B.

Returns:

utility for agent B.

isStrictlyDominatedBy

public boolean isStrictlyDominatedBy(BidPoint other)

Returns true if this BidPoint is strictly dominated by another BidPoint. A BidPoint is dominated when the utility of the other bid for at least one agent is higher and equal for the other agent.

Parameters:

other - BidPoint.

Returns:

true if "other" dominates "this".

getDistance

public double getDistance(BidPoint other)

Returns the distance between this BidPoint and another BidPoint. sqrt((Tx - Ox) ^ 2 + (Ty - Oy) ^ 2 + ...).

Parameters:

other - bidpoint to which the distance is calculated.

Returns:

distance to the given bidpoint.
